While the above may be how we begin to think about this compound, we break down the OH into pieces first:

then reorder for clarity, so we see H appears first as it is an acid.

The order in the chemical formula is sometimes:
, for example: HOCl, HOF, or rearranging as follows is also OK:

.

The latter helps us notice these are oxyacids, so we name the compound based on the Oxyacids Naming Scheme.

Traditional hydroxide names based on the elemental name of followed by the word hydroxide is also acceptable. However, this is not considered a commonly used name so it is not favored.

Examples

HOCl = HClO = Hypochlorous Acid = Chlorine Hydroxide, the base oxyanion name: ClO = hypochlorite

HOF = HFO = Hypoflourous Acid, this is an exception to the naming conventions. Other names: Hydrogen hypofluorite.
